* To apply Min. value of V
ACC
and V
CLK
, the V
DD
needs to be supplied with more than 1.5 V at least for the oscillation to
stabilize (oscillation start time tSTA).
* The Min. value of V
CLK
is the Min. voltage required to retain the time counting function. it is however necessary to maintain
V
TEM
till the oscillation of the oscillator has stabilized (oscillation start time tSTA).
* The temperature compensation stops working below Min. value of V

.
